Honestly, it isn't...most of your questions have more to do with understanding the mechanics of how namespaces, subclassing, projects and assemblies work in .NET rather than issues directly concerning MM .NET. If you were to create classes outside of MM .NET you would be having the same struggles you're experiencing now. You'd have to deal directly with ADO.NET (a HUGE learning curve) and write all your binding code by hand (a real drudge).

When I teach our MM .NET classes I can tell you that this is one of the more frustrating hurdles that developers experience, but once you understand the ground rules you can get productive very quickly. Hopefully some of the answers you've received here have helped clear things up a bit. If you haven't already done so, you may want to take a look at my book ".NET for Visual FoxPro Developers" and go through some of the chapters on using VS .NET, understanding C#, OOP in .NET, etc.
